STUDY OF THE TOTAL BACTERIAL COUNT AND NUMBER OF MICROMYCETES IN THE POULTRY HOUSE AFTER PROBIOTIC PREPARATION USE

Introduction. Antibiotics in feeding birds are dangerous due to the penetration of their residues in food. Due to the improper use of a large number of antibiotics, multi-drug bacterial resistance of microorganisms occurs. In the conditions of organic poultry farming, the use of probiotics is the most cost-effective alternative.

The goal of the work. To study changes in the total number of saprophytic microorganisms and the number of micromycetes in the air of poultry houses: 1) after aerosol treatment of the droppings with a probiotic, 2) in the group, of chicks which received probiotic solution, 3) in the control group.

Materials and methods. The study was conducted on chickens at a certified organic poultry farm in the Zhytomyr region. Groups of experimental chickens were formed by 50 chickens in each group, which were kept under a free ranging. Chickens ate organic food. It was investigated the effect of probiotic Lactobacilus plantarum AMT 12. In drinking water at concentrations of 1 ml / l of water for a week in 7 days intervals; aerosol treatment was performed in the same concentration once in 3 days. In the control group, prophylactic drugs were not used. Laboratory studies were carried out according to standard microbiological methods.

Results of research and discussion. Probiotics regulate the intestinal ecosystem of productive animals, stimulating the growth of microflora, beneficial to the intestines, and preventing the multiplication of harmful, pathogenic microorganisms. Probiotic showed a good effect on the total number of microorganisms and the number of micromycetes in the air of poultry houses. Their number decreased in both experimental groups, compared with the control.

Conclusions and prospects for further research. We have confirmed the effect of the probiotic preparation on the basis of Lactobacilus plantarum AMT 12 in a dose of 1 mg/l of water on the content of microorganisms in the indoor air for poultry. It is established that the investigated probiotic in a certain dose has antagonistic properties against a wide range of microorganisms. Its effect on reducing the total number of microorganisms and fungal microflora in the air of poultry premises and litter was revealed when it was added to drinking water and the litter was treated with its recommended concentration.

Keywords: total microbial number (TMN), micromycetes, poultry, Lactobacillus plantarum AMT 12.
